IMPROVEMENT IN GAS-GENRATING APPARATUS.

Specification forming part of Letters Patent No. 212,942, dated March 4,1879; application filed August 1, 1878.

To all whom it may concern:

Be it known that I, ERAZM J. JERZMAN- owsKI, of the city, county, andState of New York, have invented a new and useful Improvement inGas-Generating Apparatus, of which the following is a full, true, andexact description, reference being had to the accompanying drawings.

My invention has reference to a new and improved genera-tor, by means ofwhich a larger amount of gas is produced than from those previously inuse, and of better quality. In it, also, the superheaters are soarranged as to be in the hottest portion of the fire, so that the steamwhich is therein superheated reaches a high temperature. My tuyeres arealso arranged in a new method, so as to clean the gratebars and preventthe solidication which formerly resulted.

My invention will be clearly understood from the accompanying drawings,in which- Figure 1 represents an outside perspective view; Fig. 2, across-section through Fig. l on the line ma; Fig. 3, across-sectionthrough Fig. 2 on the line y y.

In the manufacture of water-gas steam of high temperature is used, andit is important to thoroughly superheat it; and I have arranged mysuperheating apparatus in the partition between two gas-generators, soas to obtain this result.

Myl improved gas-generator consists of two chambers, contained withinthe outer casing, M, and separated by the partition N, containingsuperheaters S. Each chamber is provided with a separate supply-apertureand sand-seal, F. One delivery-pipe, D, serves for both chambers.

The partition N is pierced with one or more openings, O, for the passageof the gas. The steam passing from the superheaters by pipes O isdelivered into the apparatus by tuyeres T. These tuyeres deliver abovethe conical grate-bars Gr, which l have previously patented, preferablymade of iirebrick. The downward rush of the steam upon the surface ofthese bars scours them and prevents any accumulation upon them.

Air is supplied by the pipe P to the apparatus. This pipe delivers intothe chambers H, which serve for the withdrawal of ashes from theapparatus, and are provided with tight covers.

Previous to my invention air has been customarily injected above vthesurface of theV grate-bars, and, striking against any slag or cinderwhich might fall from the coal, has been apt to melt it, and thisfalling against the grate-bars below formed clinlrers very difficult ofremoval.

By means of my improvement the air is delivered from beneath the barsand passes freely upward.

The steam is not concentrated on one point, as was previously the case.The steamtuyeres T might deliver beneath the gratebars G into thechamber H; but I prefer them in the present situation. The air deliveredto the chambers H is, of course, forced in by blower or similar forcingmechanism through the pipes I.

I find that by dividing the generator into two portions a better resultis obtained from Itis more easily handled, and the Abars Gr, the pipesP, delivering into the airchambers H, and steam pipes T, directedagainst the upper surfaces of the grate-bars, for the purpose ofcleaning such surfaces, substantially as described.
